Atmospheric scientists aboard RV Investigator will be able to measure the amount of black carbon in (soot) in aerosols in  the atmosphere with the Multi Angle Absorption Photometer (MAAP).

The MAAP passes air samples though filter paper where aerosols are collected and then measured by the change in absorption of light caused by the black aerosol particles on the filter.

Data collected using this equipment will help us to better understand the atmosphere and how particles change the way that light is absorbed by the atmosphere.

The data collected from the MAAP will contribute to reducing the uncertainties associated with the role of aerosols in climate change.
